SP4 Severe Duty

Rugged cast-iron motors with NEMA Premium® 4 (IE4) efficient, hazardous location certifications, and compliance with 2027 U.S. DOE MEM regulations.

The Next Evolution in Electric Motors

Leading the way in energy efficiency yet again, ABB Baldor-Reliance SP4 motors give you a path to energy savings that makes a difference to your bottom line. These motors achieve NEMA Super Premium efficiency across-the-line, independently of a drive. DOL or inverter duty, runs cooler, longer and quieter – now with a 48-month warranty.

 

The idea is simple. Take the best and proven AC induction design and make it better by reducing motor losses by an average of 20% while maintaining the simplicity of today's installed base of AC induction motors.

Explore the key features and benefits

<p>ABB’s SP4 technology meets the NEMA Super Premium® efficiency level in a standard AC induction motor design operating across the line, independently of a variable speed drive, or higher when powered by a VSD.</p>

Large install base

<p>There are more than 300 million industrial motor-driven systems in operation worldwide; and roughly 80% of motors still operate DOL (direct on line).</p>

Lower energy costs

<p>NEMA Super Premium® (comparable to IEC’s IE4 efficiency) can offer up to 40% lower energy loss in comparison with a NEMA standard efficient (IE2) induction motor.</p>

Government compliant

<p>Effective June 2027, Medium Electric Motors Rule driven by the Department of Energy will become effective. 100-250Hp industrial electric motor must increase to NEMA Super Premium /IE4 levels.</p>

Cooler running

<p>Able to achieve cooler running operation for longer life which means longer bearing life. This translates to longer motor life and industry-leading 4-year warranty.</p>

Inverter Duty

<p>Suitable for inverter use per NEMA MG1 Part 31.4.4.2.</p>

ABB Ability

<p>Compatible with ABB Ability smart sensor for condition monitoring.</p>

Regreasable Bearings

<p>Regreasable bearings on all frame sizes.</p>
